In aviation maintenance, what does the acronym "TBO" stand for?

In aviation maintenance, "TBO" stands for Time Between Overhaul. This term refers to the prescribed duration or total operating time that an aircraft component can operate before it needs to be removed and overhauled to ensure safety and reliability. The TBO is established by manufacturers based on extensive testing, engineering analysis, and operational data.

Understanding TBO is crucial for maintaining aircraft, as adhering to these guidelines helps prevent mechanical failures that could jeopardize flight safety. By following the recommended TBO intervals, maintenance personnel can proactively address wear and tear, thereby ensuring that the aircraft components are in optimal condition and compliant with regulations. This practice ultimately contributes to the overall safety and performance of the aircraft during operations.
